Yuanhuai YGM series diaphragm pump is a dry-running vacuum pump that achieves the vacuum pumping function by reciprocating stretching and compressing the diaphragm to cause the volume of the diaphragm chamber to change, combined with the one-way valve to switch the gas path. The pump has advanced design, high working efficiency, long service life, safety and reliability. In addition to being suitable for circulating water vacuum pumps and rotary vane vacuum pumps, it is also used in the fields of medical and pharmaceutical product analysis, fine chemicals, biochemical pharmacy, food inspection, criminal investigation technology, etc. One of the equipment in the room. Applications: Vacuum filtration, vacuum distillation, vacuum adsorption, solvent filtration, solid phase extraction, degassing, gas for compression and air conversion.
